BACKGROUND: Navigational bronchoscopy is utilized to guide biopsies of peripheral lung nodules and place fiducial markers for treatment of limited stage lung cancer with stereotactic body radiotherapy. The type of sedation used for this procedure remains controversial. We performed a retrospective chart review to evaluate the differences of diagnostic yield and overall success of the procedure based on anesthesia type. METHODS: Electromagnetic navigational bronchoscopy was performed using the superDimension software system...

Endoscopic technology has developed markedly with endobronchial ultrasonography (EBUS) having become dramatically widespread over the past 10 years. EBUS-guided transbronchial needle aspiration (EBUS-TBNA) has become an important modality for the mediastinal staging of lung cancer as well as mediastinoscopy. The combination of EBUS with a guide sheath( EBUS-GS) and virtual navigation systems, such as Bf-NAVI, LungPoint, superDimension/Bronchus system, is useful for diagnosis of small peripheral pulmonary lesions...

AIMS: Electromagnetic navigation bronchoscopy (ENB) (Superdimension) is a diagnostic and therapeutic tool in patients with lung lesions. Very small data are available about potential interference of ENB magnetic field to implanted cardioverter-defibrillators (ICDs) and any documentation of ICD behaviour if a ventricular tachyarrhythmia occurs during ENB is lacking. We tested a number of selected ICDs to assess if any interference occurs by ENB magnetic field on detection of clinical ventricular fibrillation and shock delivery...

Many peripheral lung lesions are beyond the reach of conventional bronchoscopes, and require percutaneous CT-guided or open surgical biopsy, which carry increased risks to the patient. Electromagnetic navigation bronchoscopy (ENB) is a relatively new technique, which uses an image guided localization system to direct steerable bronchoscopic tools to predetermined points within the bronchial tree. This technology allows improved access to peripheral lesions in particular. We investigated the sensitivity and specificity of ENB-guided fine needle aspiration (FNA) in the diagnosis of lung lesions...

BACKGROUND: The diagnosis of pulmonary lesions that are not bronchoscopically visible is a challenging process. Electromagnetic navigation bronchoscopy (ENB) is a new technology designed to diagnose peripheral pulmonary lesions. We sought to determine whether diagnostic yield from ENB was affected by bronchus sign, lesion location, or size. METHODS: Data were obtained retrospectively from all patients undergoing ENB at our institution since 2008. ENB was performed by 3 separate proceduralists at our institution from November 2008 until July 2011 using the superDimension/InReach system...

BACKGROUND: Electromagnetic Navigation Bronchoscopy (ENB) (InReach iLogic system; superDimension Inc) is a relatively new discipline, with promising diagnostic and therapeutic applications in patients with lung lesions. Navigation is performed in a magnetic field and, therefore, has been considered relatively contraindicated in patients with pacemakers and automated implantable cardioverter-defibrillators (AICDs). Potential risks include altering the function and shutting off the device, device damage, lead displacement, and potential overheating...

AIMS: To characterize the electromagnetic field emitted by the electromagnetic navigational bronchoscopy (ENB) superDimension(®) Bronchus system (SDBS) and to determine whether current implantable cardioverter defibrillator (ICD) systems are suitable for use in conjunction with SDBS. METHODS AND RESULTS: The electromagnetic emission of the SDBS location board were measured using a field strength meter connected to a low-frequency (5 Hz-100 kHz) electric and magnetic field analyser; the static magnetic field was measured using a three-axis Tesla meter...

BACKGROUND: The combination of electromagnetic navigation bronchoscopy (ENB), PET-CT, and rapid on-site cytopathologic examination (ROSE) for the routine diagnostic work-up of peripheral lung lesions has not been evaluated previously. OBJECTIVES: The aim of this study was to determine the accuracy and safety of ENB in combination with PET-CT and ROSE in subjects with endobronchially invisible peripheral lung lesions. METHODS: ENB was performed in 13 subjects with radiologically suspected lung cancer who were referred to our tertiary-care hospital between October 2005 and November 2006...

Electromagnetic navigation is a new technique that can be used with bronchoscopy to obtain samples of small peripheral nodular lesions and enlarged mediastinal lymph nodes. It is very versatile in that it enables both transbronchial biopsies and fine-needle aspiration to be performed. We describe 2 cases in which navigation with the superDimension/Bronchus system combined with traditional diagnostic techniques facilitated a definitive diagnosis by bronchoscopy. Electromagnetic navigation can obviate the need for more invasive diagnostic procedures such as surgery, thus saving time and money and avoiding complications...

PURPOSE: To report and describe implantation techniques and stability of metallic fiducials in lung lesions to be treated with external beam radiotherapy. METHODS AND MATERIALS: Patients undergoing radiation therapy for small early-stage lung cancer underwent implantation with small metallic markers. Implantation was either transcutaneous under computed tomographic (CT) or fluoroscopic guidance or transbronchial with the superDimension/Bronchus system (radiofrequency signal-based bronchoscopy guidance related to CT images)...

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) with biopsy under fluoroscopic guidance has enhanced the yield of flexible bronchoscopy in the diagnosis of peripheral lung lesions. However, the accuracy of ENB navigation suggests that the addition of fluoroscopy is redundant. OBJECTIVES: Data were prospectively collected to determine the yield of ENB without fluoroscopy in the diagnosis of peripheral lung lesions. METHOD: ENB was performed via flexible bronchoscopy (superDimension/Bronchus system; superDimension Inc; Plymouth, MN)...

RATIONALE: Electromagnetic navigation bronchoscopy using superDimension/Bronchus System is a novel method to increase diagnostic yield of peripheral and mediastinal lung lesions. OBJECTIVES: A prospective, open label, single-center, pilot study was conducted to determine the ability of electromagnetic navigation bronchoscopy to sample peripheral lung lesions and mediastinal lymph nodes with standard bronchoscopic instruments and demonstrate safety. METHODS: Electromagnetic navigation bronchoscopy was performed using the superDimension/Bronchus system consisting of electromagnetic board, position sensor encapsulated in the tip of a steerable probe, extended working channel, and real-time reconstruction of previously acquired multiplanar computed tomography images...

BACKGROUND: Flexible bronchoscopy is routinely utilized in the diagnosis and treatment of various lung diseases. Nondiagnostic bronchoscopy leads to more invasive interventions, such as transthoracic needle aspiration, mediastinoscopy or even thoracotomy. Electromagnetic navigation is a novel technology that facilitates approaching peripheral lung lesions, which are difficult to sample by conventional means. The navigation system involves creating an electromagnetic field around the chest and localizing an endoscopic tool using a microsensor overlaid upon previously acquired CT images...
